Graphene has unique properties, and is often added to polymers or alloys as fillers to improve the deficiencies of the matrix in terms of anti-corrosion performance. Contact with the corrosive medium; ② Graphene is a nanomaterial with a small size effect, which can be filled into the holes and defects of the coating, preventing and delaying the immersion of the small molecular corrosive medium into the metal matrix to a certain extent; ③ From an electrochemical point of view , Graphene can better passivate the coating metal, so that the corrosion resistance of the coating is further improved.

Application case: Graphene pipeline anti-corrosion coating

    First Fung customers add graphene to anti-corrosion coatings, and oil well pipelines are coated with graphene composite anti-corrosion coatings. The surface hardness of the coating reaches more than 7H, and the surface of the pipeline forms a unique micro-convex structure of graphene, which can achieve oleophobicity and anti-waxing. Effect.

    Graphene has a special two-dimensional nano-layered structure, high mechanical strength and thermal conductivity, and is the basic structural unit of carbonaceous solid lubricating materials. Experimental studies have shown that with the addition of graphene, graphene continues to cover the surface of the friction pair, and the roughness of the friction pair surface is replaced by the roughness of the graphene surface, so the lubrication mechanism gradually tends to thin film lubrication, which significantly improves the lubricant's performance. Load-carrying properties and anti-wear properties of friction pairs. Graphene has a layered structure with atomically thin thickness and low shear strength. As an anti-adhesion and anti-friction protective film for micro-nano devices of various materials, single-layer, three-layer and multi-layer graphene-based nano-lubricating films can significantly reduce Coefficient of friction and durability of small substrate surfaces.

Application Case: Lubricating Oil

    After Fenfeng customers added graphene powder to the base oil, the friction coefficient of the lubricating oil was reduced, and the wear repair and other properties were significantly improved.
